Hi,
One of our test clusters is running HADOOP 15.3 with replication level
set to 2. The datanodes are not balanced at all.
Datanode_1: 52%
Datanode_2: 82%
Datanode_3: 30%
15.3 does not have the rebalancer capability, we are planning to upgrade
but not for now.
If i take out Datanode_1 from the cluster (decommission for sometime)
will HADOOP balance so that Datanode_2 and Datanode_3 will even out to 56%?
Then i can re-introduce Datanode_1 back into the cluster.
Comments/Suggestions please?
Thanks,
Usman
